.SH NAME
gethostid \- get an identifier for the current host
.SH SYNOPSIS
.LP
.nf
#include <unistd.h>

\fBlong\fR \fBgethostid\fR(\fBvoid\fR);
.fi

.SH DESCRIPTION
.sp
.LP
The \fBgethostid()\fR function returns the 32-bit identifier for the current
host. If the hardware capability exists, this identifier is taken from
platform-dependent stable storage; otherwise it is a randomly generated number.
It is not guaranteed to be unique.
.sp
.LP
If the calling thread's process is executing within a non-global zone that
emulates a host identifier, then the zone's emulated 32-bit host identifier is
returned.
